The Application of Liquid Organic Fertilizer of Chromolaena odorata on Ratooned Rice Plants Cultivation

This research activities have been conducted in Ikur Lubuk Urban Village, Padang
Panjang Timur Subdistrict, Padang Panjang City, in March-July 2016. Activities are
demonstration plots (demplot) by planting rice that is given Liquid Organic Fertilizer
(LOF) and pruning treatment. The purpose of the devotion is to socialize the
demonstration plot so that the community can apply the pruning technology of
(forage/livestock feed) and the application of Crocober to the paddy field of medium
elevation area, Padang Panjang, so as to obtain forage feed and optimal dried rice yield.
Activities including the demplot establishment and production. The results of the
activity concluded that Crocober organic fertilizer product derived from Chromolaena
odorata is the best type and has a better quality than commercial which is distributed in
the market and already have Patent approval. Pruning can help provide forage feed for
cattle to cope with the high imports of Indonesian meat. Treatment of pruning on paddy
rice will be advantageous if pruning is done periodically with the pattern of rice
cultivation which is named by“ratoon”. Forage which is obtained in the area of 1 hectare
of rice fields per year is able to meet the needs of 2 cows for 1 year.
